NITED sTATEs PATENT oriuon HENRY VOIGHT OF NEW BRITAIN, CONNECTICUT.

PANIC 'BoL'r-Loc Be it known that I, Here; G. VoIoirr, a citizen of the United States, residing at New Britain, county of Hartford, State or" Connecticut, have invented certain new and useful Improvements in Panic Bolt-Locks, of which the following is a full, clear, and exact description.

My invention relates to improvements in looks, and particularly to that type known as panic bolt locks.

1 The object of the invention is to provide means whereby, in-the event of a panic and a heavy pressure applied against the inner side of an outwardly opening door, the lock mechanism will be released by said pressure instead of by the usual turning movement practiced in thecase of the usual knob lock.

The construction is such that a movement in either direction of the operating device will produce a ment ofthe bolt.

In the accompanyin a perspective view 0 and casing fitted with and shown on reduced scale. Fig. 2 is a view substantially full sized, of the lock case taken from the inside, the cap plate being removed. Fig. 3 is a section on approximately the line m-ac of Fig. 2.

1 represents a portion of a door arranged to swing outwardly.

2 represents a portion of the door casing.

3 is the so-called keeper and strike-plate. 4 is a latch bolt arranged to cooperate with said keeper and strike plate The bolt 4 is carried in. a casing 5 and is normally pressed outwardly by a suitable spring 6.

7 is a pivoted lever for retracting the bolt 4, said lever being suitably connected to the tail of the bolt.

l 8 is ah opening or recess in the outer side of the hub of the lever 7 adapted to receive a spindle 9, by which means the lever may be swung and the latch bolt retracted from the outside of the door 1 by the usual knob a portion of a door (not shown).

10 is a bell crank on the lever 7.

11 isa lever pivoted in the case a in a plane at right angles to the axis of the crank 10. One end of this lever 11 stands under the crank 10, the other end. projects outwardly beyond the mounting for said lever 11. 12 is a spring arranged to normally 11 in its inactive position.

engage the outer end of the lever 11 and a. second hook 16 arranged to engage the inner end of the lever 11. A suitable clearance space is provided between the hooks l5 and .16 to aiiord proper clearance for the lever '11. The acti J11 of the spring 12 on the lever 11 serves to hold the latter in such a position as to normally ma nta n the lowerend of the lever l t outwardly and away from the door.

From the foregoing, it will be seen that if the lower end of the lever 14 is either pulled out away from its normal position or pushed same upon the lever 11. In other words.

in relatively thereto, 'the action will be the" said action will be to tilt the lever 11 in a direction to lift the bell crank 10, swing back the lever 7 and retract bolt 4.

In. constructions like the above, it is preferred to have an operating bar 14: connected with-the free end of the lever 14; and extending across the face of the door, as best seen in Fig. 1. Y

14 is a swinging arm mounted in a suitable bracket 14 to carry the adjacent end of the bar 14?. When such a bar is provided, its movement either toward or away from the door will serve to retract the bolt 4, thus freeing the door and permitting it to be opened by outward pressure. This is a distinct advanta e, because if for any reason should the'loc fail to operate by movement of the bar 14* in one direction, it may be operated bymoving said bar in an opposite direction; furthermore, the bar 1 L may be employed to close the door from the inside.

W'hat I claim is:

1. In a lock of the character described, a spring actuated latch bolt, an operating device'thcrefor, includin a hinged lever arranged to move toward and from the door, and operative means of connection between bolt for retracting said bolt by either movement of said lever.

22. In a lock of the character described, a

spring actuated latch bolt, an operating'dcvice therefor, including a hinged lever arranged to move toward and from the door, and operative means of connection between said lever and said latch bolt for retracting said bolt by either movement of said lever,

said means of connection includin a sec-- ond tilting lever pivoted intermediate its length.

3. In a lock of the character described, a spring actuated latch bolt, an operating desaid means of connection including a second tilting lever pivoted intermediate its length,

'and two hookscarried by said first mentioned lever for engagin said second lever on opposite sides and near each end.

4. In a lock of the character described, a spring-actuated latch bolt, an operating de- Vice therefor, including a bar extending across the face of the door and hinged so as to move toward and fronrthe door, and operative means of connection between said bar and said latch bolt for retracting said bolt by either movement of said bar.

5. In a lock ofthe character described, a spring-actuated latch bolt, an operating device therefor, including a bar extending across the face of'the door at the inner side and hin edto move toward and. from the door, and

said'bolt by either movement thereof, sai means of connection including a tilting lever pivoted intermediate its len th.

6. In a lock of the character-described, a

operative means of connection be tween-said bar and said latch bolt forretracting said hinge for engaging said lever on opposite sides and near opposite ends.

7. In a lock, the combinationof a bolt,-

means for operating said bolt from one side of a door and including a bar extending across the faceof said door and arranged to operate said bolt by a movement either to or from the door. o

8. In a lock, the combination of a spring pressed bolt, means for retracting the same"- from one side of a door, and including a bar extending across the face ofthe door and arranged to operate said bolt by a movemer t either to or from the door. HENRY oivoieiir.
